Answer:
option C: accurate
Explanation:
this is because daily updated website contains the up to date information.
Answer:
a.
<u>Given Data :</u>
Data rate of each Line (Channel) = 9600 bps
Total lines need to be multiplexed = 10
<u>Solution:</u>
Total Capacity of Synchronous TDM = Data rate of each line x Total Lines
= 9600 bps x 10
= 96,000 bps
= 96 Kbps
Explanation:
In time division multiplexing, multiple channels (Lines) can transmit data over the medium on different time slots. In synchronous TDM, equal time has been allocated to each channel to transmit their data over the medium. so the total capacity required for 10 lines synchronous TDM is 96Kbps.
Answer:
b.
<u>Given Data:</u>
Data rate for each line (Channel) = 9600 bps
Total lines need to be multiplexed = 10
Average TDM link utilization = 80% = 0.8
Each link busy for the time = 50% = 0.5
<u>Solution:</u>
Capacity of Statistical TDM = data rate x number of Lines x each channel duration/Average utilization of TDM
Capacity of Statistical TDM = 9600 bps x 10 x 0.5/0.8
=60,000 bps
= 60 kbps
Explanation:
In TDM, if we want to limit the capacity of TDM and each channel that need to be multiplexed. we can limit the utilization of the TDM by limiting its transmission time of each channel and also the capacity of TDM.

Explanation:
it's common sense
Answer:
Option d is the correct answer for the above question.
Explanation:
- Authentication is a process that enables the user to enter the system. This process helps to secure the data. It is because with the help of this only valid users can enter the system. In this process, the system asks some unique information from the user which can only be known to the valid user.
- Some systems put two types of authentications one is some information about the valid user and the other is a fingerprint scan that takes the data of the user finger and matches with their user name and password. If it matches then only he can enter into the system.
- The above question asks about the mechanism which is used for multifactor authentication. This authentication is known as a fingerprint scan. So the option D is the correct answer while the other is not because:-
- Option 'a' states about the username which is used in the first authentication.
- Option b states about pin which can be used in the place of username.
- Option c states about the security question which is used when the user forgets the password.
